Two of the nastier hits Pittsburgh linebacker James Harrison delivered on Cleveland players last Sunday are getting all the publicity.

Browns center Alex Mack said there were more.

“If you watch the game film, (Harrison) was doing that to everyone on every play,” Mack said Thursday. “People would be on the ground and he would try to spear them. There’s a play on film where (running back) Peyton Hillis is tackled and he comes up and spears him. It’s like you’re being cheap, you’re being dirty.”

Harrison was fined $75,000 for his hard, helmet-to-helmet hit on Browns wide receiver Mohamed Massaquoi, one of several devastating blows on an unusually violent Sunday of head-high collisions around the NFL. Harrison’s hit on Massaquoi — and one that knocked out Browns Pro Bowler Joshua Cribbs on a running play — helped prompt Commissioner Roger Goodell to crack down and impose significant fines and suspensions players for hits to the head and neck.

Mack said Harrison wasn’t just hurting the Browns. He was doing damage to himself.

“The helmet-to-helmet with Cribbs is a little more innocent, to some extent,” Mack said. “You’re still leading with your head. It’s a dumb move no matter what you do. First of all, you’re ruining your own brain and you’re damaging other people.

“It’s your brain.”

Mack is the first Cleveland player to publicly denounce Harrison as “dirty” and question his tackling tactics. In fact, a few of the Browns, including Cribbs and Hillis, said they didn’t feel Harrison’s hits warranted any punishment.

On his Twitter page, Cribbs wrote that he didn’t believe Harrison, a former teammate at Kent State, was trying to hurt him.

“I have no bad will towards LB James Harrison,” Cribbs tweeted. “That’s what he’s supposed to do: knock people out. It’s what makes him one of the best. ... He is still my boy ... It is unfortunate, but our sport is brutal. We will both bounce back & compete again real soon. ... Oh yeah & we play each other twice!”

Browns Head Coach Eric Mangini said Cribbs and Massaquoi have improved. He hopes both players will practice Friday.

Players are on high alert for flagrant hits in the wake of a $75,000 fine on Harrison.

Asked if he expects more flags than usual, Mangini said, “Typically, if there’s a point of emphasis, that point of emphasis spikes so I’d imagine it will spike.

“Some weeks, it’s ‘tackle too deep,’ some weeks it’s hits on the quarterback. Whatever the point of emphasis, you can pretty much guarantee it’s going to spike.”
